Ok as some of you may remember when I first got my X3 and tunes I had a hell of a time. I ended up sending the unit back to SCT for them to have a look at it (reformat) after my stock tune was lost some how.
That leeds me to my latest problem. Lately when I have been driving my truck has been running like crap. No low end and very poor milage. No low end like when I floor it even on loose traction the tires don't spin. When you step on the gas the truck starts off slow until the rpm's get up higher and then it takes off sort of like a 2 stroke with a power band.
I thought it was a problem with my tow tune because when I have the trailer on there is little to no low end power. I should also say the poor performance happens while using a performance tune as well.
So my question is does anyone know can this all lead back to when SCT made me a new stock tune ? Is that possible ? Or problems with the other tunes? Has anyone else had this happen to their truck ? I have tunes from TP and an AF1 intake. The truck was running well and getting good milage and power but it seems like all of a sudden like I say now low end power and poor milage.
Any ideas or replys are appreciated......
